Plant Features

Carnegie Hyacinth Bulbs (Hyacinth Orientalis) produce gorgeous, fragrant blooms in crisp white shades. A spring bulb staple, hyacinth are perfect for lining pathways or in a spring container mix. Let the the foliage die back naturally, and they will come back year after year. Recommended spacing for fall planted Carnegie Hyacinth bulbs is 6 inches apart at a depth of 6 inches.

Planting Instructions:

  • - Plant bulbs in the fall, 4-6 weeks before the ground freezes.
  • - Dig a hole 6 inches deep, and place the bulb with the pointed end up.
  • - Space bulbs 4-6 inches apart to allow for proper air circulation.

Soil Preparation:

  • - Prefers well-draining, loose, and slightly sandy soil.
  • - Mix compost into the soil for added nutrients and improved drainage.
  • - A slightly acidic to neutral pH level between 6.0 and 7.0 works best.

Watering Specifics:

  • - Water bulbs immediately after planting.
  • - During active growth in spring, water moderately, keeping the soil moist but not soggy.
  • - Reduce watering once the blooms fade and the foliage begins to die back.

Fertilizer Type:

  • - Use a balanced, slow-release fertilizer at planting time.
  • - Reapply fertilizer in early spring as new shoots begin to emerge.
  • - Avoid over-fertilizing as it can cause excessive foliage at the expense of blooms.

Pruning and Care:

  • - Deadhead spent flowers to prevent the plant from focusing energy on seed production.
  • - Allow foliage to naturally die back as it replenishes the bulb for next year's growth.
  • - Apply mulch in late fall to protect bulbs from freezing temperatures in colder climates.

Additional Pest Management:

  • - Protect bulbs from rodents by using wire mesh or covering with mulch.
  • - Aphids may appear on the plant; spray with insecticidal soap or a strong jet of water to remove them.

Blooming Indicators:

  • - Carnegie Hyacinths bloom in mid-spring, typically in April.
  • - The blooms are a brilliant white, creating a stunning contrast with other spring flowers.
  • - Blooms last for 1-2 weeks depending on weather conditions.

Light Requirements:

  • - Thrives in full sun (6-8 hours of direct sunlight) but tolerates partial shade.
  • - In warmer climates, partial shade helps prevent the flowers from wilting too quickly.

Temperature Tolerance:

  • - Hardy in USDA zones 3-9.
  • - Requires a cold period (below 40°F) for successful blooming.
  • - In zones 8-9, pre-chill bulbs in the refrigerator for 10-12 weeks before planting.

Companion Plants for Carnegie Hyacinth:

  • - Pansies: Provide a colorful, low-growing companion to the tall white spikes of Carnegie hyacinths.
  • - Daisies: Offer a fresh and natural look alongside the pure white blooms of Carnegie hyacinths.
  • - Tulips: Tulips in complementary colors such as red or pink work well with white hyacinths for a layered display.
  • - Grape Hyacinths: Add color and variety, with their smaller, deep blue blooms pairing nicely with Carnegie's white.
